To a whom it may concern:

Be it known that I, WILLIAM A. MA'rrtoLrs, a citizen of the UnitedStates,A residing at Cumbola, in the county of Schuylkill and State ofPennsylvania, haveinvented certain :new and useful Improvements inPadlocks, of; which the following isl al specification. Y My inventionrelates to padlocks, and has for its object to provide a lock. that isdiflicult to unlock except to one familiar with its construction. Y Mylock consists of a cylindrical casing an a shackle pivotally mountedthereon. The end of the shackle that enters the casing is provided withaiscreW-threaded bore torreceive the end of the lock-bolt, which isprovided with screw-threads to lit said threaded bore. At the end of thecasing through which the key is inserted is provided adoor orkeyhole-guard that may be closed lover the keyhole and cannot be openedexcept by one familiar with the lock, lthe opening of the door dependingupon the manipulations of buttons on the shackle and various otherparts, that will be fully explained hereinafter..

Another feature of my lock is acatch to y prevent the manipulation ofthe locking-bolt when in a locked position, said catch being operated bythe same parts that are manipulated to open the door over, the keyhole,so that should the door be broken open in an attempt to pick the lockthe latch will still be inoperative.

The construction and advantages of my invention' will fully appearhereinafter/and by reference to the accompanying drawings, in which-Figure 1 is aside view of my lock; f Fig.;y 2,

I Inthe drawings similar reference-characters indicatecorresponding parts throughout the severalvievvs.Y i Y j Y. v v

' 1 represents a tubular casing, n nade` preferably ofjsteel, soasresist breaking, and 2 the shackle, pivotally mounted, by means of aslot 3 and 'pin 4to a strap shrunk on said casing 60 1. Itis understoodthat the slot 3 permits a slight play of the shackle when being insertedin and withdrawn from the casing 1.

Theend of shackle 2 is provided with a screwthreaded bore 6 to receivethe screw-threaded 65- end 7 of the lock-bolt 8 -inlocking Behind saidscrew-threaded end7 is a shoulder 9, that lits snugly the bore of casing1 and serves to guide the end 7 in projecting the bolt.

y1Q represents a spindlesecured to or inte- 70 gral with the shoulder9.v Mounted on spindle 10 lis a sleeve 11, having at the end adjacent toshoulder 9 a shoulder 12, that also fits snugly the b ore of casing l.

l 18 represents a ring secured to shoulder Y75 12 and spaced ap'arttherefrom by means of blocks 14. f 15 represents a pin on spindle 10that normally bears; against ring 13, but which in operating the boltpasses through hole 16 in 8O shoulder 12 and rests against either sideof recess 17 formed in shoulder 12 and the adjacent end of the barrel ofsleeve 11.

18 represents an expansible coil spring mounted between shoulder 9 andring 13. S5 The outer end of sleeve 11 is formed with a shoulder 19, thesurface of said end being rounded at its edges. y y

20 represents notches in the end of sleeve end of the bolt formed tocorrespond tosuch IOO projections.

22represents thekeyhole, which consists of A a tube having a iiange 23,that is secured to the bore of casing 1.

From the above description it will be understood that when the lock-boltis in the position shown in Fig. 2 the sleeve 11 will rotate on thespindle 10. To retract the bolt, the key after being inserted in thecasing and the projections 21 fitted into notches 2() is pushed inward,sliding sleeve 11 on spindle 10 against the resilience of spring 18. Theinward movement of the key will be arrested by the shoulder 12 coming incontact with the pin 15. The key is then turned on its aXis until thepin 15 enters hole 16, when the sleeve is again pushed inward asufficient distance to allow the pin to pass through said hole and thenturned in the direction to unscrew the end 7 from bore 6, the pin 15contacting with the side of recess 17 and causing the whole bolt toturn.

24 represents the keyhole-guard hinged to strap 5 and having a catch 25secured thereto, which is adapted to be engaged by a plate 26; slidablymounted between disks 27, secured to the inner side of strap 5, saiddisks 27 and plate 26 being perforated in alinement with the keyhole 22,as shown at 28, the lower side of the perforations in the disk beingnotched, as shown at 29, to receive the end of catch 25. The upper endof plate 26 is formed as a pin 3() to depress the plate when it isdesired to open the door forming the keyholeguard 24, 31 representing aspring to throw the door outward when the catch 25 is released.

32 represents springs to raise the plate 26 when pressure on pin 30 isreleased.

33 represents a lever-catch fulcrumed on rivet 34, secured in casing 1and having its end 33a adapted when in a normal position to engageshoulder 19, being held in this position by means of leaf-spring 35,secured in shackle 2.

36 represents a dog having a rectangular bore 37 in which is mounted therectangular pin 38, inserted in circular holes 39 in strap 5. The freeend of dog 36 is forked and has the narrow portion 40 of link 41 seatedtherein, while the other narrow portion 42 of said link 4l is insertedin the forked end 43 of angular lever 44, the ends of said forkedportion 43 being bent toward each other slightly, so as to hold thenarrow portion 42 in place. Said angular lever is fulcrumed by means ofleafspring 45, mounted in shackle 5, and has its outer end formed with ahood 46, that covers the pin 30 when in its normal position.

It will be understood from this description that when the outer end oflever 44 is raised the dog 36 is drawn along the top of levercatch 33,thus raising its end 33a out of engagement with the shoulder 19, so asto permit the sleeve 11 to slide on spindle 10, as hereinbeforedescribed in operating lock-bolt 8. At the same time hood 46 will beraised, so

that the head of pin 30 is exposed, and it may be depressed, so as toopen the guard 24 to permit insertion of the key.

In order to prevent raising lever 44 and hood 46 except by one familiarwith the mechanism of the lock, I provide a'securing means therefor,which is hereinafter described. The top and end of shackle 5 is slotted,as shown at 47, and mounted therein are two pins 48 and 49, held inplace by rivets 50 and 51, re-

spectively, that ride in circumferential grooves 52 and 53 in said pins.The end of said pins that protrude from the top of the shackle areformed with buttons 48a and 49, respectively. The pin 48 is providedwith a barrel portion 54, having one segment thereof recessed, as shownat 55, while the other segment has a spiral groove 56 therein, beginningat one side p at the bottom of said recess and ending at the other sideat the top thereof. The other pin 49 is formed with a iiange 57, spaceda short distance apart from the head 49L and leaving a circumferentialgroove 58 therein for the purpose hereinafter set out, the ange 57 beingprovided with a notch 57 D1 59 represents a lever fulcrumed on rivet 60,having one end riding in the groove 56 and recess in pin 48, while theother end is adapted to seat in notch 57a when the parts are in theposition shown in Fig. 2.

59L is a spring to hold the lever in the locking position shown in Fig.2.

61 represents a catch for holding pin 48 from turning which is securedto the shank of button 62, which is slidably mounted in bar 63, mountedin groove 58 and under button 48. When in a locked position,catch 61 isseated in a notch 64 in pin 48 and prevents it from turning; but whenthc button 62 is pressed toward button 49a the end of the catch leavesnotch 64, and the pin may be rotated.

65 represents a coil-spring to normally hold the catch in engagementwith notch 64.

66 represents a dog pivotally mounted on the end of shackle 5 and havinga spur 67 thereon against which bears a spring 68 to normally hold it inthe position shown in Fig. 3.

69 represents a lever-catch which normally engages the rear side of dog66, as shown in Fig. 2, and when in said position its other end rides ingroove 58.

70 represents a spring to hold the lever in the position shown in Fig.2.

The operation of this part of the lock isas follows: The button 62 isfirst pressed toward button 49, which, as stated above, releases pin 48,and by turning button 48 lever 59 is actuated, so as to cause its end toleave notch 57, and pin 49 is thus released to rotation. When the pin 49is turned so that notch 57 L is directly beneath the end of lever 69,said lever may be depressed, so as to disengage its other end from dog66. When so released, spring 68 throws the end of dog 66 upward, and theparts just described will be in the po- IOO IIO

sitions shown in Fig. 3, and the lever 44 and hood 46 may be raised.

To resecure the partsjust described, the dog 66 is swung to the positionshown in Fig. 2. The spring will then lift the end of lever 69 upwardthrough notch 57 a into groove 58, while its other end bears againstsaid dog. The pin 48 is then turned to the position shown in Fig. 2,which releases lever 59 to the action of spring 59", which raises itsend against theflange 57. Then when pin 49 is turned the end of lever 59will enter notch 57 1, and the device will be in the position shown inFig. 2.

It will of course be understood that the buttons 48 and 49a may bemarked so as to tell when they are in the proper positions to lock andunlock the parts.
